As I understand it, Norm used the range plug and receptacle to replace
the connectors on the dock, not the boat-side connectors.
If you have a 30-amp connection to shore power, I would recommend the
SmartPlug boat-side receptacle, the SmartPlug shore power code, and use
either the conventional twist-lock connectors on the shore end (if the
marina won't let you change their power point on the dock end of the
cord) or the range plug and connector (if the marina management agrees).

Unfortunately, the 50-amp version of the SmartPlug stuff isn't available
yet.
On board the boat, be sure to have a reverse polarity detector and
alarm. And, _especially if you ever dock at fresh-water marina_, an
ELCI (Equipment Leakage Circuit Interrupter) per ABYC E-11.11. Another
Very Good Thing would be an isolation transformer.

on the dock? I would much prefer to make my own cable if I can get everything
to match up.

For the years I lived at a marina I copied the shrimpers of Charleston SC
and used a range plug (the plug and receptacle used by electric kitchen
ranges) on the dock end of my shore line. In the first marina (Stono
Marina Charleston SC) the owner understood the wisdom of the thing and at
the second one (Green Cove Springs FL) I installed my own power outlet box.
The boat end of the shore line had crimped and soldered ring terminals
bolted to the ship's wiring.
Range plugs/receptacles are commonly available, cheap, can carry sufficient
amps, have lots of copper with a large contact area and can be taken apart
to be cleaned and greased annually.
I cannot remember ever having a problem with them, while I do remember a
few twist-lock connectors that let the magic smoke out.

The biggest problem with the current twist lock power connectors is
the limited connection area of the connectors. A straight push
connection with a locking collar would be far preferable.
